We currently have a bug where a period on the Swedish (Svenska) keyboard isn’t recognized as a decimal on our site. For some reason, the Swedish period isn’t a “culturally aware” one for some reason. This can lead to errors when inputting weight on the website or in the app.

Entering a comma as a decimal separator using the English code page will also trigger a “The field Weight must be a number.” We have this bug in the backlog of issues to fix, but our developers are currently working on other tasks. You might be able to get around this by switching your region and language to English (I had to restart my computer to get the changes to stick for Swedish), and then try to change your weight and add a decimal with this keyboard applied.

Have the same problem on Chrome over Win10. Cannot enter decimal value for weight, tried “.” as well as “,”, “The weight must be a number”. Going to iOS app, only “,” is available as a decimal separator, and gets ignored (xx,x gets interpreted as xxx).
